We implement our projects on Legacy Software with a tool our own tool: Survol, an open-source project that you can freely download and use. This is a graphic tool that anyone can use.

It can display for example the tree of processes and subprocesses ...

... or a directory and its subdirectories ...
... or the shared memory segments and the processes mapping them ... and everything can be combined in graphic reports, everyone can understand.

An output mode is speficially tuned for printed reports.

Here are some technical links about Survol:
